Thread-topic:	How many memory can assign to xen0?

Hi all,

I found Xen booting would hang, if I assign a little large memory (>1900M) to 
Xen0.
The hang happened just after printing "load initrd..."

Firstly I try it in a 2G physical memory box. The results:
dom0_mem=1000M  booting ok
=1024M          booting ok
=1800M          booting ok (xm info show there are 66M free memory left)
=1900M          booting hang
=2000M          __booting hang__
=2048M          __booting hang__

Then I also try it in a large memory box (8G).
Dom0_mem=2048M          __kernel panic__ when booting xen0 kernel.
Dom0_mem=1024M          booting okay.

The changeset is the latest 9774.

Best Regards,
Yongkang (Kangkang) 永康
